MECHANICAL MOVEMENT.

Application filed August 9, 1919.

To all whom it may concern Be it known that I, HnRMAN G. PAPE, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Mechanical Movements, of which the following is a specification.

This relates to a mechanical movement in which there is a driving member and a driven member, both revolubly mounted and preferably so as to oscillate, these movements being connected so that the one is moved by the other through a tension device which oscillates on an axis perpendicularto the direction of the movement of one or both of the said members, as is described in Letters Patent No. 1,190,451, of July 11,

1916. In the present case, however, the driven and driving members, as hereinbefore stated, are pivotally mounted to oscillate and are mounted on the same pivotal point instead of on separate and distinct points, as shown and described in Letters Patent No. 1,246,646; one of the objects of the present invention being the provision of a mechanical movement in which both the driving and driven members are mounted on a common pivotal point and connected by te sion devices in such a manner that a predetermined revoluble movement of the driving member exerts a predetermined tension on the tension device so that the driven member is thereby actuated with a quick snap movement.

In carrying out my present invention, I

may also employ an auxiliary driving member together with means for returning the auxiliary driving member automatically to an initial position'in which, by the next successive movement thereof, it is adapted to impart another movement to the driving member, and which in turn is imparted to the driven member, the construction being such that when the parts are made to oscillate, the auxiliary driving member is re turned to a position which is. beyond the line of the center of pull, so that this oscillating movement is made possible; these features of the invention being the same as those shown and described in Patent No. 1,216,483, granted February 20, 1917.

Furthermore the structure in the present case is such that the auxiliary driving mem ber, as well as the driving and driven members, also is revolubly mounted on the same Specification of Letters Patent.

pivotal point. Furthermore, in accordance with the present invention, I may also employ an actuating member through which the driving member is moved by the auxiliary driving member, and in this structure, the actuating member is also revolubly mounted on the same pivotal point as the auxiliary driving member, the driving memher, and the driven member. It will furthermore be understood that the several parts of the mechanism comprising this invention, when the parts are made to oscillate, are provided with suitable stops to limit the extent of the movement thereof.

The mechanical movement comprising the present invention, is illustrated in one form thereof in the accompanying drawing, in which,

member. l Flg. 11 1s a central cross section thereof.

Referring particularly to the drawing, it

will be seen that in carrying out this invention, I employ a base upon which the parts of the mechanical movement are mounted, and which is provided at either side of the center and at the required distance therefrom with stop members 11 and 12. In a suitable position, the base 10 is fitted with a pivot post 13, and revolubly mounted on the pivot post 13 is a driven member 14. This driven member 14 is shown in detail in Figs. 12 and 13, and preferably comprises a plate of sheet metal having acentral aperture 15 adapted to receive the pivot post 13 and a recess 16, the purpose of which will be hereinafter explained. In the driven member 14 there is a small hole 17, the purpose of whichwill also be hereinafter explained. In the requiredpositions, this driven member also includes tongues 18 and 19 adapted to contact relatively with the stops 11 and 12, as hereinafter described, so as to determine the extent of the movement of this oscillating driven member as herein illustrated. Furthermore this driven member is also provided with a lug 20 placed centrally between the tongues 18 and 19 and appreciably nearer the center of the member, and the function of this lug will also be hereinafter described.

Mounted to turn freely on the pivot post 13 there is a collar 21 and suitably secured to this collar 21 in a position spaced from the driven member 14, there is a main driving member 22. This main driving member 221s illustrated in detail in Figs. 10 and 11.

It is preferably made from sheet of metal and provided with a central aperture adapted to receive a portion of the collar 21 and to which it is suitably fixed so as to turn therewith. 1n the required positions, this main'driving member is also provided with oppositely disposed arms 23, 24, in corresponding edges of which there are notches 25 and 26. Centrally between the arms 23 and 24, this main driving member is also provided with a projection 27, the extremity 28 of which is turned so as to lie parallel with the body of the drivin member, and

is provided with a small hole 29. v

Connectingthe driven and main driving 'members, as hereinbefore described, I employ a'tension device which preferably comprises a spring 30 having a coil or loop 31 centrally disposed with one end of the spring engaged in the hole 17 in the driven memberand the other end of the spring engaged in the hole 29 in the main driving member. This spring, as clearly illustrated in Figs. 2 and 5 of the drawing, extends through the recess 16 in the driven member and oscillates on an axis which is perpendicular to the direction of the movement of the said members, the action being the same asthat shown and described in Patent No. 1,190,- 451, to which reference has hereinbefore 'been'made, and vis such that after a predetermined movement has been imparted to the main driving member in given diree tion, the tension is applied to the spring which moves the driven member in the opposite direction with a quick snap action.

Referring to Fig. 1, assuming that these parts are in their normal positions, the tongue 19 lies against the stop 11, hearing against the inner face thereof, whereas the notched edge of the arm 24 of the driving member bears against the upper edge of this stop 11. Now by imparting a predetermined movement in a counter-clockwise direction by any suitable means applied to the arms 23, 24, or eitherpf them, the driving member may be oscillated to assume the position shown in Fig. 4, in which the stop 12. By reversing the movement of the driving member, these parts maybe returned to their initial position, as shown in Fig. 1.

Together with the parts hereinbefore described, 1 may also employ an auxiliary driving member 32 which is illustrated in detail in Figs. 8 and 9 of the drawing. This auxiliary driving member is also pref erably made of a plate of metal and'is provided adjacent one end with an aperture 33 adapted to receive a portion of the collar 21, so that the auxiliary driving member 32 will be free to turn thereon. This member is also provided at the opposite end with an extension top 34 provided centrally with a recess or notch 35, Ina suitable position, this member is also provided with an ex tension. or tongue 36 extending at right angles thereto and provided with slots 37 and 38, and a notch 39, as clearlyseen in Fig. 9.

When in position in the apparatus, the reverse face of the auxiliary driving member bears against the obversevface of the main driving member, and the edge of the main driving member lies within the recess or notch 39. 40 and 41 represent springs. One end of the spring 40 is connected in the lug 20 in the driven member and the.

opposite end of this spring 40 passes through the slot 37 and is turned at its extremity sov through the slot 38, and at its extremity is.

turned over so as to engage the opposite face of the extension 36, the overturned end of the spring 40 being indicated at 42, while the overturned end of the spring 41 is indicated at 43.

I also employ an actuating member indicated at 44 as illustrated in detail in Figs. 6 and 7. Like the other parts employed in this mechanical movement, the actuating member 44 is preferably made of. a plate of thin metal. It is furthermore provided with an aperture 45 to receive a portion of the collar 21 so that when mounted thereon it will turn freely. At one end and in oppositely disposed positions, this actuating member is provided with oppositely disposed shoulders 46 and 47, while at the other end, there is a transverse shoulder 48. When in position in the apparatus, the shoulders 46 and 47 bear against thedriving member 22 and span the auxiliary driving member 32, while the shoulder 48 extends beyond and over the inner portion of the driving member 22 so that the ends thereof, that is, the ends of the shoulder 48 are adapted to engage respectively with the notches 25 and 26 in the arms 23,24'of the driving member 22.

As illustrated in the drawing, I have shown a flexible pull chain 49 engaged at one end in the notch 85 in the tongue 34 at the outer end of the auxiliary driving member 82 and passing through a conduit or chain guide 50 suitably connected to the base 10 upon which the parts of the movement are mounted.

In the operation of the parts forming this mechanical movement, assuming the same to be in the position indicated in Fig. 1, a pull upon the chain or cord 49 is first imparted to the auxiliary driving member 32 and against the action of the spring 41, this auxiliary driving member turning on its pivotal point until it first contacts with the shoulder 47 of the actuating member 44. It will be noted that the right hand end of the shoulder 48 of the actuating member as shown in Fig. l with the positions of the parts of the movement as shown in Fig. 1 lies in the recess 26 of the arm 24 of the driving member 22. In the continued movement of the auxiliary driving member by the continued pull on the chain, the auxiliary driving member acting against the shoulder 47 of the actuating member oscillates this actuating member in a counter clock-wise direction and the actuating member in turn moves the driving member in the same or a counter clock-wise direction. This counter clock-wise oscillating movement of the driving member puts a tension on the spring 30 which is increased as the oscillating movement of the driving member is continued until this tension is sutlicient to cause a quick snap oscillating movement to be imparted to the driven mem ber 14, the driven member 14 being thus turned or oscillated on its pivotal point in a clock-wise direction. It is furthermore to be noted that with the parts in the position as shown in Fig. 1, the arm 24 of the driving member bears against the stop 11, the arm 24 contacting with the upper edge of the stop, while the edge of the tongue 19 contacts with the inner surface of the stop. In the movement hereinbefore described, the parts are moved to the position shown in F ig. 4, in which it will be noted that the arm 23 of the main driving member bears against the upper edge of the stop 12, whereas, the edge of the arm 18 bears against the inner surface of this stop 12 so that the stops 11 and 12 limit and determine the extent of movement of both the driven member and the main driving member. After the parts have been moved to the position shown in Fig. 4, when the pull chain is released, the action of the spring 41 returns the auxiliary driving' member and the auxiliary driving member returns the actuating member to a position in which the auxiliary driving member is carried beyond the central line and this position is determined by the spring 40 which stops the return movement of the auxiliary driving member so that these parts are then in a position upon the chain or cord being pulled again to actuate the parts in the same manner but in an opposite direction as it is believed will be readily understood, as will also the fact that when the parts are again actuated by another pull on the chain that they will be returned to the original position or that shown in Fig. 1.

It will furthermore be understood that while. I have herein shown and described my improved mechanical movement as havmg associated therewith an auxiliary driving member and an actuating member moved thereby for turning the main drivingmemher, that these parts, namely, the auxiliary driving member and the actuating member, may be dispensed with and suitable means employed for actuating the main driving member in any other desired manner.
